Not too small and too long charging connector wires. Such big connection resistance. Too thin, then rushed over battery voltage out on much.
Connected to the battery the best good contact. Otherwise rushed over battery voltage out on much.
If the 5V input voltage is high, such as 5.2 or even 5.5, will result in insufficient charging current is 1000mA, this is normal. High voltage chip fever will automatically reduce the charging current, not to chip burned. Chip at work about 60 degrees fever is normal. After the charging current is large.
Enter the reverse has no effect on the chip, but the output (battery terminals) reverse will burn the chip, please note that buyers.
